Be if known that I, Joux J, Mmmm', o eitizenbi the United States, residing at Anderson, in the county of` Madison and State ol" indiana. have invented newA and useful lm n'ovexnenls'in Annealing-Boxen; and I do" ll full, einer, and exact denrripton of the invention, referentielminy,` had to the accompanying drawings, and to the letters of referenve marked there-v 'lhis invention relntes to s neet-metabolinealing boxes ol the einem that are used in sheet-'mills andV tin- )lote miils in anneeiing; sheetn ofvlnetalianil the invention has pnr- 'tieularreferenee tothe part that is designed to be laced upon a stnnd to cover `the sheets while )eine heated and then slowiy'eooled inl the annealing pmeess..

The objects of the invention are to provide a Sheetxnetal-nnnealing boxthat may be Vrelied 'on to'hold its shape under the severe service to which auch articles are neeeqsarily in vparticularwill have`a top w n'eh when heated .tothe highest degree in use will not 'sag of its own weight and therefore will not :anse the sides of the box to, bulge outwerdly,V and to provide n construction whereby isheetanetl-:mnealing boxes muy be rendered more durable vund eeononlieid than thi" heretofore in use. J @Vith the above-1nentioned and minor ob 'ents in view the invention consists in a novel eilt-up sl|eetn1etal-annealing box having a` crowning or archedtop provided with novel nrt-hes for the support thereof, the box being prm'idedwith tie-rods that are welded to the sides und topA mrt of the box andalso'lmfing ponts l'or the ireet support-of the ercbezl'and tie-bnrnfor the arches; and the inventioneon-l nist-e, further. in the novel parts und the eem-v binations and nrrangei'nentsof part,as here.- inaiter particularly deseribod undelaiinid.'

A suitable number of tie-rods7 :is ll Il ll H, extend across the upper poi-Lion ol ilie' box-body, and: the' ends of thc tierods nre welded to the sides D and D ol the box-boi Iv In this construction the upper portions oF 1 hibox sides are irst perforated to receive tho ends of the tie-rods, andthe perforetions arc counters'unk at the outer ends thereof'. tie-rodsextend throu li the sides of the bodv and are. upset while ot in the countersunli `erforations, soi-as to form headsf.
